A power plant anti-blocking dust suppression noise reduction coal transfer system

Abstract

The invention discloses an anti-blockage, dust suppression and noise reduction coal transport system for a power plant. The coal transport system comprises an upstream conveying device, a coal falling pipe and a downstream conveying device, wherein the discharging end of the upstream conveying device is used for feeding materials into the feeding hole of the coal falling pipe; the discharging hole of the coal falling pipe is used for feeding the materials to the feeding end of the downstream conveying device; the coal falling pipe comprises a throat hopper and a three-arc-segment coal falling pipe. The three-arc-segment coal falling pipe is designed on the basis of discrete element simulation EDEM, and has high coal type adaptability. By adopting a flow channel, the blockage of coal particles can be well prevented; meanwhile, the collision angles of the coal particles and a pipeline are reduced, and the advantage of reducing noise is realized. The three-segment coal falling pipe is spliced by adopting a deflection way, and a hydraulic damping device is arranged on a bend collision point, so that wear of the pipeline can be reduced effectively. Meanwhile, the speed of the coal particles is limited, soft landing of the coal particles and a downstream conveying belt is realized, impact on the conveying belt is reduced, and the production of dust is reduced.

Description

technical field [0001] The invention relates to an anti-clogging, dust-suppressing, and noise-reducing coal transfer system for a power plant. The system has the advantages of preventing blockage, suppressing dust, and reducing noise, and belongs to the technology of power plant transportation and environmental protection. Background technique [0002] my country is a large coal country with abundant coal resources. Coal-fired power generation is still the main form of power generation in my country. From entering the power plant to making coal into pulverized coal and sending it to the boiler furnace for combustion, a very important link is transportation. Coal transportation and treatment in power plants usually use tape multi-stage transfer and inter-stage treatment. However, as the installed capacity of domestic coal-fired power plants increases, the demand for coal also increases, which brings certain challenges to the transportation of coal within the plant.
